From my experience, it is ideal if you have a DD team that is composed of highly technical people, people with well-developed soft skills and finally a group of people that is somewhere in-between. Regarding certain aspects of DD, such as financial DD and legal DD, it is better if you have very technically adept people take care of this aspect. On the other hand, there is also a need for a holistic view of the entire DD process. This aspect is better if done by people with well-developed soft skills, as they have to converse and evaluate every step of the way, both internally as well as with the target.
